This is one of the various purposely made cables that one can opt for when assembling the AIAIAI headphones. It is made reasonably well however mine ended up with the shielding worn out after about 2 years at the connection between the cable and the connector with the interior cables becoming the only thing holding the whole thing together. I'm at my second cable and will see how long this one will last.
Audio quality is good.
Interchangeability is bad as you'll need AIAIAI cables for the AIAIAI headphones since they come with a specific jack connector.
Price wise it is on the steep end as I don't feel that it is worth the €20, however since the headphones are still in perfect working order I had to purchase a replacement.
